Wiretrustee SATA is a Raspberry Pi Compute Module 4 (CM4) carrier board for DIY network attached storage (NAS). It is the first such board to directly transfer data via the native CM4 PCIe interface, and thus avoids unstable USB-to-SATA connections.

Wiretrustee SATA features four SATA ports, one gigabit Ethernet port, and a small form factor (100 x 100 mm), making it possible to build a tiny home NAS. It supports 2.5" and 3.5" drives, both SDDs and HDDs. Whereas 2.5" drives can be plugged in directly, 3.5" drives require additional extension cables.

In addition to a fully assembled and tested board, we plan to offer DIY kits for building your own complete NAS.

Compatible with All CM4 Variants

Wiretrustee SATA supports all the Compute Module 4 variants thanks to a microSD card slot (for CM4 light) and a firmware flashing mode via the top-side USB 2.0 port (for CM4 with eMMC).

Open Source

Wiretrustee SATA board has been verified to work with Raspberry Pi OS with SATA drivers enabled in a cross-compiled kernel. All the necessary installation instructions and scripts (including RAID setup), as well as board schematics and PCB layout, will be published on our website.
